BACKGROUND/AIMS: Pancreatic cancer sometimes occurs during the course of chronic pancreatitis. This study aimed to identify risk factors for developing pancreatic cancer associated with chronic pancreatitis. METHODOLOGY: The incidence of pancreatic cancer developing in 218 patients with chronic pancreatitis and clinical features of the chronic pancreatitis patients who developed pancreatic cancer were studied. RESULTS: Nine patients developed pancreatic cancer. Average period from the diagnosis of chronic pancreatitis to the diagnosis of pancreatic cancer was 9.6 years. All pancreatic cancers were diagnosed at an advanced stage. Only 2 patients had been followed-up periodically. There were no significant differences between chronic pancreatitis patients who developed pancreatic cancer and those who did not in male/female ratio (3.5 vs. 8), average age on diagnosis (65.0 vs. 56.5), alcoholic/non-alcoholic chronic pancreatitis (1.6 vs. 2.6), smoking habits (62.5% vs. 70.7%), diabetes mellitus (77.8% vs. 54.4%), and continued alcohol drinking (37.5% vs. 53.1%). CONCLUSIONS: Over the period examined, 4% of chronic pancreatitis patients developed pancreatic cancer. Sex ratio, onset age, etiology, smoking habits, diabetes mellitus, and continued alcohol drinking were not significant risk factors for developing pancreatic cancer in chronic pancreatitis patients. Periodic follow-up due to the possibility of pancreatic cancer is necessary in chronic pancreatitis patients.
